African-American InventorsA Sampling of African-American Inventors and Their Inventions

BLOOD BANKThe idea of a blood bank was pioneered by Dr. Charles Richard Drew (1904-1950). Dr. Drew was an American medical doctor and surgeon who started the idea of a blood bank and a system for the long term preservation of blood plasma (he found that plasma kept longer than whole blood). His ideas revolutionized the medical profession and saved many, many lives. Dr. Drew set up and operated the blood plasma bank at the Presbyterian Hospital in New York City, NY. Drew's project was the model for the Red Cross' system of blood banks, of which he became the first director.

CARVER, GEORGE WASHINGTONGeorge Washington Carver (1865?-1943) was an American scientist, educator, humanitarian, and former slave. Carver developed hundreds of products from peanuts, sweet potatoes, pecans, and soybeans; his discoveries greatly improved the agricultural output and the health of Southern farmers. Before this, the only main crop in the South was cotton. The products that Carver invented included a rubber substitute, adhesives, foodstuffs, dyes, pigments, and many other products.

CRUM, GEORGEThe potato chip was invented in 1853 by George Crum. Crum was a Native American/African American chef at the Moon Lake Lodge resort in Saratoga Springs, New York, USA. French fries were popular at the restaurant and one day a diner complained that the fries were too thick. Although Crum made a thinner batch, the customer was still unsatisfied. Crum finally made fries that were too thin to eat with a fork, hoping to annoy the extremely fussy customer. The customer, surprisingly enough, was happy - and potato chips were invented!

DORTICUS, CLATONIA JOAQUINClatonia Joaquin Dorticus was an African-American inventor who received many patents. He invented an apparatus for applying dyes to the sides of the soles and heels of shoes (patent # 535,820, March 19, 1895), a machine for embossing (contouring the paper of) photographs (patent # 537,442, April 16, 1895), a device that helped develop photographs (patent # 537,968, April 23, 1895), and a leak stopper for hoses (patent # 629,315, July 18, 1899).

RILLIEUX, NORBERTNorbert Rillieux (March 17, 1806-October 8, 1894) was an African-American inventor and engineer who invented a device that revolutionized sugar processing. Rillieux's multiple effect vacuum sugar evaporator (patented in 1864) made the processing of sugar more efficient, faster, and much safer. The resulting sugar was also superior. His apparatus was eventually adopted by sugar processing plants all around the world.
